I used a terminal command, I haven't seen it in the GUI: midclt call system.advanced.update '{"kernel_extra_options": "pcie_aspm=off"}' https://www.truenas.com/community/threads/missing-advanced-kernel-options.102479/

You can find more details in this post: https://forums.servethehome.com/index.php?threads/lenovo-thinkcentre-thinkstation-tiny-project-tinyminimicro-reference-thread.34925/page-71#post-402456 I got these results with display enabled. Running headless saves a few Watts. I added Kioxia BG4 256GB...

Sorry, I don't have a good constant load I can use. I measured my other system (Dell Wyse 5070) and my results matched other values I've seen online (~4W). My P330 has i5-8500T, 2x8GB RAM and 3 nvme SSDs (one in a 2230 WiFi slot). Right now it runs Ubuntu Desktop 22.04 LTS for testing purposes...

Yes, I was able to ping the other host, the interface was up in Ubuntu. It’s also possible that my cheap power meter is not very accurate, on such small loads.

Hi, sorry for a delay, I finally measured it. P330 tiny, i5, headless, idle + powertop --auto-tune. Total system consumption, measured at the wall. No SFP+: 5.9W 1x 3m Copper DAC: 6.0W

Intel X710-DA2 also supports ASPM and allows C7 to be reached on my Tiny P330 system. It added 3W in total to idle power consumption with nothing connected to SFP+ ports.

The board I got, uses a standard 6 pin PCIe. https://www.aliexpress.com/item/1005005670883185.html BTW. I ran some iperf3 tests and did ZFS replication of most of my data, no issues so far on ConnectX-3.

You can also get or build a pikvm and use with a normal PC: PiKVM - Open and inexpensive DIY IP-KVM on Raspberry Pi Edit, some PCs also have vPro, which also allows for remote access.

Maybe someone will find it useful. After enabling IOMMU in the bios, it's possible to pass the onboard SATA controller to a VM (like TrueNAS) in Proxmox installed on NVMe.

I used this adapter in my Lenovo Tiny with a 2230 SSD as a boot drive: https://www.aliexpress.com/item/1005005117932695.html But I don't know if it will fit in this system.

I finally experimented with PCIe. I have two Gigabyte boards and tested two 10g network cards: Mellanox ConnectX-3 Single SFP+ and Intel X710-DA2. Both of these cards got detected on both of these boards, but not perfectly. I'm using a Ceacent adapter and an 85Ohm cable. On the first board CX-3...

Chielos had a success. I ordered these adapters too and I’ll try connecting a 10g card in a few days. Edit: Looks like PCIe expects impedance of 85 Ohms, and SAS 100 Ohms. https://www.mouser.com/pdfDocs/987652-0234.pdf I think 85 Ohms cables with are the correct ones in this case.

You need to enable SMT (Symmetric Multithreading Technology) in BIOS, it's off by default on this board: Advanced -> AMD CBS -> Zen Common Options -> Core/Thread Enablement -> Agree -> SMTEN -> Auto After this change I can see 8 threads in the OS.

Does it support x4x4 PCIe bifurcation? Would it be possible to add 2 NVMe SSDs without a switch?

Could you also try with a different ashift value, like 13?

Have you tried with 2 modules in blue slots? Sorry for a silly question, but is the fan spinning?

Mine works with 2x 4GB Micron 2400T RDIMM modules (MTA9ASF51272PZ), I had laying around, without any issues. Management interface initially showed a single 16GB module, but it updated to the correct values, when I booted the system.

Have you tried running any kind of a stress test, like iperf, and checking kernel logs for errors? Could you please try? I'm wondering about signal integrity and how stable it is.

Something like that, in a standard form factor and with more SATA ports would be perfect for me: https://arace.tech/products/plamshell-next-h2 Ryzen Embedded has built-in support for 2x 10G Ethernet, and even ECC: https://www.amd.com/en/products/specifications/embedded/21261+11411 More SATA...

I haven't tested it, but there's also AOC-STGF-i2S, which is based on X710, but looks shorter.
